Andy - you're not the only one. i still have that feeling - sometimes with guys that are young enough to be my sons! last week i got triggered in a weird way at the school where i teach by 11th and 8th grade boys. both are taller and stronger looking than me and i feel like a child when near them.
"Tell your heart that the fear of suffering is worse than the suffering itself... And that no heart has ever suffered when it goes in search of its dreams, because every second of the search is a second's encounter with God and with eternity." - Paulo Coelho
